In an interface arrangement between a first component group supporting a tool holder and a second component group supporting a machining element in a central opening for releasably accommodating the first component group, a shift lever element provided with engagement members is disposed rotatably on the second component group and provided with engagement and release elements for releasably retaining the first component group in the central opening of the second component group so as to permit a rapid exchange of the first component group by another group with a new tool.

A connection device for assembling together a receiver first section member presenting an inner cavity, and a fastener second section member presenting a groove having a constricted opening. The connection device includes a cage forming a pair of jaws for coming into engagement in the groove. The device also including a resilient drive mechanism for urging a spacer member between the jaws so as to space them apart in such a manner as to come into engagement with the groove through the constricted opening; and a pivotable lever that pivots about a pivot pin, the pivotable lever including a lever arm and a thrust head that engages the spacer member so as to move it against the force exerted by the resilient drive mechanism on the spacer member.

In a structure, which securely attaches a component to an opening portion in a plate-shaped member without stripping or turning over the plate-shaped member, each of a pair of mount members includes a first engagement portion engaged with a rear surface side of the plate-shaped member and a second engagement portion engaged with the component. The component includes projecting portions to be fitted between the mount members to enable fixing against coming off by engagement of the second engagement portion and the component. The projecting portions inhibit the mount members from moving so as not to come off the opening portion. Since the second engagement portion is formed from the multiple step portions engageable with the component, engagement with the component may be done even if plate thickness of the plate-shaped member varies, enabling fixing without backlash and improving versatility to the plate-shaped member having different plate thickness.

A work tool coupler for a work vehicle may include a rigid body, a retention pin, a four-bar linkage, and a lever. The retention pin may be configured to engage a work tool when the coupler is in an engaged position. The four-bar linkage may include a first member pivotally connected to the retention pin and at least one of a second member and a third member, the second member pivotally connected to at least one of the first member and the third member, the third member pivotally connected to at least one of the first member and the second member and a fourth member, and the fourth member pivotally connected to the third member. The lever may be attached to the fourth member.

A device for quick splicing of a display screen is provided. The device includes a left assembly and a right assembly. The left assembly includes a rotation fixing seat, a rotation angle seat, a rotation locking mechanism, and a step angle-adjusting and clamping mechanism. The rotation angle seat can lock with the right assembly, and is rotatably connected to the rotation fixing seat. The rotation locking mechanism is disposed between the rotation fixing seat and the rotation angle seat. When the rotation locking mechanism is unlocked, the rotation angle seat can rotate relative to the rotation fixing seat; and when the rotation locking mechanism is locked, the rotation angle seat is fixedly connected to the rotation fixing seat. The step angle-adjusting and clamping mechanism is disposed between the rotation angle seat and the rotation fixing seat.

Fabrication of a latch mechanism is provided for latching a field-replaceable unit within an enclosure. The latch mechanism includes a pivotable latch coupled to the field-replaceable unit via a pivot, at a first side of the unit, and a spring member associated with the enclosure. The spring member is engaged by the latch and deflects with rotating of the latch from an open position to a latched position. The pivotable latch includes the first end and a second end, with the pivot being disposed closer to the first end than the second. The deflecting spring member facilitates provision of positive pressure on the unit directed towards a second side of the unit opposite to the first side to facilitate, for example, fixedly coupling a first connector at the second side to a second connector associated with the enclosure when the unit is latched within the enclosure.

A removal assembly includes a main body, a positioning element, an elastic element, an actuating element, and a wrench element. The positioning element is movably disposed in an inner space of the main body, including a clasp part and an oblique side surface, and the clasp part extends out of the main body. The elastic element is disposed between the main body and the positioning element. The actuating element is pivotally installed in the inner space of the main body, including a pressing part and an abutting part, the pressing part extends out of the main body, and the abutting part abuts against the oblique side surface of the positioning element. The wrench element is connected to the main body, including a fixing part and a pivoting part.

An attachment element for mounting a vehicle seat on a vehicle structure includes a sleeve, at one end of which a lever element is arranged, and an element which can be a hollow cylinder and which has at least two wing-like extensions lying opposite one another, and which at least partially surrounds the sleeve. Also, a method is described for mounting a vehicle seat on a vehicle structure by using at least one fastening element.

An automatically-lockable, shock absorbing dock for a portable computer, the dock comprising: a top plate configured to receive a portable computer, said top plate comprising: an automatic locking mechanism for securing the portable computer to said top plate, a set of connectivity ports, and a port replicator configured to connect the portable computer to the set of connectivity ports; and multiple pairs of shock absorbers connected to a bottom surface of said top plate and configured to connect to a target surface, wherein each pair of shock absorbers is coaxially-positioned and connected to opposite sides of said bottom surface, and wherein each shock absorber has an essentially equal resiliency in its x, y and z axes.

A CPR device having a base member configured to be placed underneath a patient, a chest compression mechanism configured to deliver CPR chest compressions to the patient, a support leg configured to support the chest compression mechanism at a distance from the base member, a clamp mechanism coupled to the support leg, and a release mechanism coupled to the support leg and the clamp mechanism. The clamp mechanism is configured to attach the support leg to a lock component of the base member in a latch-closed configuration and to release the support leg from the lock component in a latch-open configuration. The clamp mechanism is further configured to transition from the latch-closed configuration to the latch-open configuration when the lock component of the base member impacts an external portion of the clamp mechanism without the release mechanism being pulled away from the base member.
